"I went to pick up the diamond, it wasn't there anymore," said Kaufmann, who co-owns the business. "I looked around and I didn't see it. I grabbed his head, opened his mouth, looked inside and nothing there and I felt him swallow."

Kaufmann scrambled to figure out how to get the $20,000 rock out of Soli's stomach.

A veterinarian assured Kaufmann it would pass naturally, which meant checking every day.

"It wasn't that pleasant," Kaufmann said. "I had to go through it, which was not that nice. My cousin, who's a dentist, he thought it was really funny. He brought me a box of rubber gloves."

And it didn't come easy.

Kaufmann endured three days of sifting before finding the diamond in the roughage.

"It was like hitting pay dirt, like in the gold rush," Kaufmann said.

This bizarre story gained international attention.

The National Enquirer picked it up, and on Monday, the BBC called for a live interview.

Just going to the local bank is an adventure for Kaufmann, now.

"Somebody said, 'Oh this is the dog that ate the diamond," Kaufmann said. "So he's getting to be more well-known."

Kaufmann said he opted not to buy the diamond but return it instead -- a decision he insisted had nothing to do with how he finally got his hands on it.
